derivatives and tricyclic analogues with a fused additional ring on the nitrogen atom of the benzoxazine moiety have been prepared and evaluated for their cardiovascular effects as potential antihypertensive agents. The imidazoline ring was generated by reaction of the corresponding ethyl ester with ethylenediamine. Affinities for imidazoline binding sites (IBS) I(1) and I(2) and alpha(1) and alpha(2)
已经开发了2-(4,5-二氢-1H-咪唑-2-基)-3,4-二氢-2H-1,4-苯并恶嗪衍生物和在苯并恶嗪部分的氮原子上具有稠合的附加环的三环类似物。制备并评估其作为潜在的降压药的心血管作用。咪唑啉环是通过相应的乙酯与乙二胺反应生成的。评估咪唑啉结合位点(IBS)I(1)和I(2)以及α(1)和α(2)肾上腺素能受体的亲和力,以及对平均动脉血压(MAP)和心率(HR)的影响自发性高血压大鼠。除少数例外,MAP上活性最高的化合物是对IBS和alpha(2)受体具有高亲和力的化合物。在这些化合物中,化合物4h是最有趣的,现在与它的对映异构体一起,
